Multiple chamber package



Oct. 28, 1952 M. R. FIELDS MULTIPLE CHAMBER PACKAGE Filed July 8, 1950 INVENTOR. fi/ao/ 1? 526% The two-compartment package may be used for liquids which are incompatible, or are mutually destructive. The package may also be used for compact handling of an unstable solid and a solvent therefor. The size of the two containers may be varied to suit the requirements of the individualpreparations.

Others may readilyadapt the invention for use under various conditions of service, by employing one or more of the novel features disclosed or equivalents thereof. As at present advised with respect to the apparent scope of my invention, I desire to claim the following subject matter.

I claim: H 1

1. A multiple-compartment package comprising, in combination: an outer container having an openin thereinto and an inner container having an opening thereinto; a single resilient closure common to both containers; said closure comprising an outer peripheral skirt adapted to seat on the outlet of said outer container, an inner circular portion separated from said skirt by an annular groove, and a stopper for said outer container below said groove, having an axially aligned circular recess therein adapted to hold and seal said inner container; said closure adapted to release said inner container into said outer container by axial inward displacement of said circular portion, whereby said stopper is distorted along the wall of said outer container openin and said circular recess is distorted laterally, releasing said inner container; and an outer cover aseptically sealing said closure, said cover being a cup-shaped cap sealed over said 7 tainer having an opening, and a cylindrical inner container having an opening, disposed in said outer container; a single resilient closure common to both of said containers sealing the contents thereof individually apart, said closure comprising a flat top portion covering the opening of said outer container and extending to the outer edge of the wall of said opening, a stopper portion I adapted to fill said opening in said outer container extending below said flat top, a recess in said stopper adapted to receive telescopically said inner container, sealing the opening therein and holding said inner containerin spaced relation to said outer container, and an annular groove in said flat top of smaller diameter than said opening in said outer container, whereby inward axial movement of the circular plane described by said groove distorts said stopper along the Wall of said opening'and laterally distorts said stopper recess releasing said inner container into said outer container to permit admixing the respective contents thereof.

3. A multiple compartment package comprising, in combination: a large container havin a circular opening; a small container having a circular outer contour small enough to lie coaxially in said large container opening, leaving an intervening annular space; and a closure of material yieldable with respect to shape but not with respect to volume, including an annular portion encircling one end of said small container and lying inside the lip of the large container opening; a septum covering the open end of the small container and integrally united around its periphery with said annular portion; a sealing flange overlying the lip of the large container opening and integrally united with an edge of said amiular portion; the inner diameter of said flange being greater than the outer diameter of said septum to leave an annular groove between them; said septum terminating in a plane offset slightly below the plane of the upper surface of said flange; and a metallic closure cap overlying and pressing down on said flange and engaging an outer irregularity of contour in said large container to hold it in place.

4. A closure for a multiple compartment package comprising, in combination: an annular portion; a central-septum integrally united around its periphery with said annular portion; a sealing flange integrally united with an outer edge of said annular portion; the inner diameter of said flange being greater than the outer diameter of said septum to leave an annular groove between them; said septum terminating in a plane ofiset slightly below the plane of the upper surface of said flange, said annular portion extending below said sealing flange and adapted to seat internally in one compartment and externally on the other compartment to seal both said compartments.

5. A multiple compartment package comprising, in combination; a large container having a circular opening; a small container having a circular outer contour small enough to lie coaxial with said large container opening and leaving an intervening annular space; and a closure of yieldable material common to both of said containers. including an annular portion encircling one end of said small container and seated inside the large container opening; a septum covering the open end of the small'container and integrally united around its periphery with said annular portion; a sealing flange overlying the'lip of the large container opening and integrally united with an edge of said annular portion; the inner diameter of said flange being "greater than the outer diameter of said septum to leave an annular groove between them; said septum terminating in a plane ofiset slightly below the plane of the upper surface of said flange.

6. A closure for a multiple compartment package consisting of a pair of telescoping containers, comprising, in combination: an annular portion adapted to encircle the mouth of the smaller of said containers and stopper the mouth of the larger of said containers; a central septum integrally united with the upper, inner edge of said annular portion; a sealing flange for the lip of said larger container extending radially from the upper outer edge of said annular portion; the inner diameter of said flange being greater than the outer diameter of said septum to leave an annular groove between them; said septum terminating in a plane ofiset slightly below the plane of the upper surface of said flange.
